    摘要： A self-cutting, undercutting dowel (1) is formed of an axially extending anchor rod (2) with a head part (3) leading in a setting direction (S) of the dowel and an axially extending sleeve (5) laterally enclosing the anchor rod (2). At its end facing in the setting direction, the sleeve (5) has expansion sections (7) separated from one another by axially extending slots (6). The sleeve (5) can be driven over the head part (3) relative to the anchor rod (2) so that the expansion sections (7) flare radially outwardly. At least one of the expansion sections (7) has a tooth shape at its end facing in the setting direction forming a cutting edge (10) for cutting an undercut in a receiving material for the dowel. The cutting action is effected by rotating the sleeve (5). The cutting edge (10) is located at a side edge (11) of the expansion section (7) leading in the rotating direction (R) of the sleeve (5) and the cutting edge is inclined to an axis (A) of the sleeve at a first angle (.alpha.). The expansion section (7) with the cutting edge (10) has a trailing side edge (12) inclined relative to the axis (A) of the sleeve (5) at a second angle (.beta.). The sum of the two angles (.alpha.,.beta.) is less than 160.degree..

    摘要： A method and the device for fiber-optic measurement of the absolute value of the pretensioning in a highly loaded mechanical structural component part are based on the measurement of the phase displacement of a light wave caused by the strain-induced birefringence in a single-mode light waveguide 4 which is embedded between two metallic disks or washers 3a, 3b. Since the measurement results are ambiguous modulo-2.pi., serial or simultaneous measurement with two light wavelengths .lambda..sub.1, .lambda..sub.2 is used according to a first method variant of the invention. The quantity of 2.pi. periods can be unequivocally determined within a predetermined measuring range by means of comparing the two measurement results. The evaluation is preferably effected according to a quadrature or phase step method, known per se. According to second method variant, the light waveguide 4 is irradiated with polarized white light. The phase difference of the two linear modes due to the influence of force on the structural component part is compensated for in a compensation device 20. The control signal required for the compensation of the path difference is evaluated as a measurement for the force. The compensation method has the advantage that no monochromatic light sources are required.

    摘要： The present invention discloses a method and an apparatus which enables one to obtain definite non-modulo-2.pi.-dependent measurements wherein a method for the fiber-optic measurement of force, which is based upon the strain-induced birefringence of a single-mode light waveguide, provides a compensation method for the phase differences of two linear modes of the exiting light waves, which are caused by the force acting on the light waveguide and the consequent change in birefringence. In one embodiment of the method, a liquid crystal cell, the birefringence effect of which can be controlled electrically, is used as a compensation element. The maximum of an autocorrelation function, which occurs as an image, and the respective voltage at the liquid crystal cell, are evaluated as a measurement for the birefringence which is to be compensated for and, accordingly, for the effective force. In an alternate embodiment of the method, the two partial waves are directed transversely relative to the propagation direction of the wave fronts by an optical component with linearly space-dependent birefringence. The autocorrelation function can then be obtained as a spatial coordinate and can be plotted electronically by a line detector such as a line array. The location of the maximum of the autocorrelation function is, under certain defined conditions, a measurement for the birefringence which is caused in the light waveguide by mechanical tension from which the magnitude of the force, which acts on the force sensor, can be calculated.
